My ,invention relates lto a coin-controlled apparatus, especially devised to bve used in a connection with a liquid dispenser, the present application being a divisionot my pending application, Serial `Number 679,292. filed `December' 8th, 1923, for a coin-con trolled Aliquid dispenser. Y

The object of my invention is to enable the dispensing of the liquid 'bythe insertion of coins of different valuesfY A vfurther object is to so disposethe coinoperated mechanism that it Will `simultaneously control the flling of the dispensingtank as Well as the emptying of the same. 1n the accompanying drawings forming part of the Vfollowing description V Figure `l is a` ksectional elevation of part of a `'gasoline dispenser wherein-the coin-controlled operating mechanism ris mounted;

Figure 8 is a detail retaining mechanism.

Referring to Figure 1, 10 is a section of cfa part of the diska standard surrounding a tube (not shown) intended to convey liquid to a measuring reservoir. `Upon lthe standard Vl0 is mount-V eda coin 'trunk L1. Below this coin trunk, a disk A'l2 is mounted 'to l:rotate around Ythe stand pipe 10. The disk is provided With a deep groove 13 vinto Which is'inounted to rotate an operating flever `14, `said/lever being mounted at the bottom of the groove preterablyrfby a separate collar 15, united by means of bolts 16. Lever 14 extends outside the standard --10 and ,travels into a slot 17 v'in a -casing 18, Which ,casing is mounted in a groove 19 l:formed in the 'coin trunkll. Lever 14 yisprovided Withfa hand piece 20, as shown.

In order .to clause lever -14 to retract independently of disk y12,11 provide a spring21 (see Figure 3). This spring is shown fcon nected to `the lhead of one of the bolts l16 and to a ,hookj22 on the inside of'casing 18.

`So tar, it has been said that thedisk l12 rotates about the standard 10 and thatlever 14V rotates about the disk "12.` In order to rotate the disk`12'by means .Otlever 14, vit is necessary yto VprovidedV a means of tem'- porarily locking the same to effect this'r'o-V tation. This is done -by'means ofv Ycoins of several denominations, vtvvo oi which are shown -in the present instance at 23 (see Figure 4.).V These coins are `of respective values of rtwenty-tive land iiftyncents.A The coins are introduced inhslots 2,5 and 26 in the coin trunk V1l, whichV coin trunk, as previously stated, is astened'to the standard by means ofset'screivs 24 and forms part of a circular flange extending outside Casing 18. It'vvill Abe noticed'that the twenty-vefcent slot 25 'is setl in advance of the iifty-centislot 26 aV spa'ceeopu'al to the difference invalue ofthe liquid dispensed. The coin slots are curved as shoWnin Figure 5. i i

So as to prevent `the insertion of a coin of different denomination Vthan that intended for the particular slot, I form underneath the curve acham-ber V25 ","having anV opening into the coin s101325, the coin slot being providedY lWith guiding*grooves"25b positioned over the opening." .Whenever ,a coin of properdenominatioii is inserted into the opening 25C, it will Yenga-ge 'the grooves 25b in the Vcoin slot v25 and' ollovvthe same over chamber y25a until'it reachesV the vslot inthe disk 12. Should a coin of'smalier diameter than the one intended'ior the' particula: slot ybeinserted, it will dro into the chamber 25a as litsdiameter Will e less than that required to "keep it Within the grooves 25h. The chamber 25 communicates outside the standard so ythat the Wrong may be returned-toits owner.

The Ilocking -o lever 14 to the disk 12 is laccomplished -by the tace ofY the coin in the following manner: l/Vhena'cin isinserted in slot 25, lit falls down into a slot 27 in lthe disk 'l2`vand' When a Ytitty-centV coin is ldropped linto vslot 26, it'vvill Hfall into la correspondingV slot 28, also in disk 12'. 'It should be'understood, of course, thatffthere areopposite-the'tvventyfve cent slot 25, sin slotsdisposed around disk 12, making/'autotal of one dollar and fifty cents worth of liquid dispensed, and that there will be live slots in the same disk opposite the fiftycent slot 26. lt may be remarked that the coin slots in disk 12 extend on both sides of groove 13 and as the thickness of this groove is less than the diameter of the coins inserted, they will project on both sides of the lever 14 and rest against the walls of the slet in the disk, thereby locking lever' 14 to the disk 12 until such time as they drop into the coin box 29, which box may also be fastened to the standard 10 by means of set screws SO. It will be understood, of course, that when the lever has travelled the whole path, the coin will drop into the coin box through a slot 32.

in order to prevent the coin inserted in disk 19 from being retracted, means are provided to hold the coin until it reaches the end of the travel of the disk. For that purpose, l provide pawls 353 and 34 (see Figure 4), pawls 33 being mounted in cavities 35 in the coin trunk 11 and pawls 34 being mounted in similar cavities 36 formed around the coin box 29. lt will be un derstcod that there is a set of pawls back of every slot in the coin boX. Each pawl is provided with a spring 37 to keep the saine against the face of disk 12. Back of each slot in the disk is formed depres-v sions 38 to allow the pawls to fall behind the coin whenever the disk is in position to receive them. As the pawls rest in the disk, the back face of the coin will be retained by them and the disk so that the coin cannot be moved backward on the retraction of lever 14.

As soon as the coin falls into the coin box, the disk 12 is disengaged from the lever but it is 'essential that the disk will remain in position until the liquid purchased is fully dispensed. For that purpose, it becomes necessary to temporarily lock disk 14 by some means, which in the present instance comprises the following arrangement: A number of depressions 39 (see Figures 2 and 7) are made in the face of disk 12, into which a pawl 40, fulcrumed on the trunk V11, enters. These depressions are so shaped to allow the pawl to disengage itself when free from pressure. Therefore, in order to hold them in pressed engage ment, l provide a rod 41 passing through a perforation 42 in the coin trunk 11 and connected to a lever 43 fulcrumed at 44 (see *igure 8), which lever extends over the outlet 45 where it is connected to a rod 46 supporting cup (not shown) positioned in the path of the liquid iiow. The cup is provided with a perforation suliiciently large to drain the liquid contained therein after the flow ceases. TVhenever the cup is filled with liquid, its weight will depress lever 43 and forces rod 41 on pawl 40 to maintain the same in locked position. The moment the cup is empty, rod 41 will be released and pawl 40 will easily be disengaged from the depression 39, and the disk being` now freed, will retract to its normal position by means of spring 47 connected at 4S to collar 49 lined to disk 12 and to the coin trunk 11 at 50. it will thus be seen that lever 14 can only operate disk 12 when a coin is inserted in either of the slots mentioned.

The mechanism to which this coin slot is applied is fully described in my co-pending application above referred to but in order to fully understand its working in lation therewith, l have shown in Figure 1 a section of a valvelopening rod 51, resting on disk 12. This rod is actuated vertically by means of a cam 52, circularly mounted on disk 12 so'that when the same is rotated, it will engage the end of rods 51 and raise the same to open a valve (not shown), intended to draw the liquid purchased. Y Y

To obtain liquid, the purchaser'y inserts a coin of either a twenty-five or fifty cent value. The twenty-live cent coin is inserted in a slot 25, which is positioned midway or the travel of the lever 20. ln such a case, the lever 2O moves freely from its resting point to opposite vthe slot 25, when its freeV path is obstructed by the coin in that slot which has dropped into the disk carrying cam 52, which operates the valve rod 51. Consequently,the twenty-live cent piece willV cause thecam to raise the valve of the tube in the gasoline container delivering a twenty-live cent value. lWhen a ,fifty-cent piece is used, it is dropped into the slot 26, which is positioned a distance backof slot 25 equal to the value of the distance of travel for the delivery of a twenty-live cent value. The fifty-cent piece, consequently, locks the lever 20 immediately at its resting Ypoint and when this lever is operated, it will travel double the distance of that of the twentylive cent value. Consequently, fifty-cents7 worth of liquid will be dispensed. In Fig ure 3 the position of slots 27 and 2S are indicated and as the opening for the twentylive cent slot is just equal to the diameter of the coin, it will be impossible to insert a fifty-cent piece there and vice versafor the titty-cent slot as its diameter is too great to adapt the twenty-five cent piece which when falling into the disk'would not lock the lever. lt will be understood that the groove in disk 12 is wider opposite the fifty cent slot than it is opposite the twenty-iive cent slot. rhe moment the lever has reached the limit of its travel, the coin will drop into a coin box. rEhe disk, being then free, will return to its original position, when a repetition of the operation above described may be made.

What I claim is l. In a coin-controlled apparatus ot the class described, a standard, a stand pipe mounted therein, a trunk box around said Standard, a coin box also mounted on said standard below said trunk box, a disk revolvably mounted on said standard between the coin trunk and coin box, a lever mounted to rotate in said disk independently ot the same, coinV slots in said disks coinciding with slots in the coin trunk so as to lock said lever by means of coins inserted through said coin trunk in said disk.
